Title: Prebiosignature Molecules Can Be Detected in Temperate Exoplanet Atmospheres with JWST Authors: A. B. Claringbold, P. B. Rimmer, S. Rugheimer, O. Shorttle First Author’s Institution: Institute of Astronomy, University of Cambridge, Cambridge, UK Status: Accepted to AJ The search for life in the universe has always been a driving force for interest and development of astronomy and the space sciences. Far from tales of little green men and aliens on Mars, today’s scientific investigations into extraterrestrial life usually involve trying to find the traces that life leaves behind in the l ..read more

Title: Long-term follow-up observations of extreme coronal line emitting galaxies Authors: Peter Clark, Or Graur, Joseph Callow, Jessica Aguilar, Steven Ahlen, Joseph P. Anderson, Edo Berger, et al. First Author’s Institution: Institute of Cosmology and Gravitation, University of Portsmouth, Portsmouth, PO1 3FX, UK Status:  Submitted to MNRAS [open access] The universe is a violent place. Right now, at this very instance, a star that has wandered too close to its central black hole is probably getting shredded apart in a spectacular display of light and energy. These events are called Tid ..read more

Title: An Enigmatic 380 kpc Long Linear Collimated Galactic Tail Authors: Dennis Zaritsky et al. First Author’s Institution: Steward Observatory, University of Arizona, Tucson, AZ Status: Submitted to MNRAS When studying the histories and interactions between the galaxies in our universe, the structures known as galactic tails can often be key signatures in uncovering the pasts of the island universes that make up the cosmos we observe. Studies of the trailing tails of gas and dust that galaxies sometimes leave behind have triggered revolutions in our theories of galactic mergers and galaxy ev ..read more

Title: Detecting Exoplanets Closer to Stars with Moderate Spectral Resolution Integral-Field Spectroscopy Authors: Shubh Agrawal, Jean-Baptiste Ruffio, Quinn M. Konopacky, et al. First Author’s Institution: Department of Astronomy, California Institute of Technology, Pasadena, CA, USA Status: Accepted to the Astronomical Journal [open access] Thus far, the vast majority of known exoplanets have been discovered indirectly, using techniques such as the transit or radial velocity methods, which allow us to infer the presence of planets based on their effects on their host stars. However, to ..read more
